On July 29, 2005, FDA received a Citizen Petition from Biostratum, Inc. Biostratum is the manufacturer of Pyridorin, which contains as its active ingredient a salt of Pyridoxamine (i.e., a component of vitamin B6), and which is the subject of an Investigational New Drug Application ("IND"). Pyridorin is intended for therapeutic use to slo...

The rate enhancement of the polymer over that of simple Pyridoxamine was a
steep function of the length of the alkyl chains added, in polymers with roughly
the same percentage of alkylation and of Pyridoxamine attachment. At pH 7.0 and

IsoK/LG form and should therefore be more effective in vivo than hydrophilic
compounds such as Pyridoxamine. The greater efficacy of salicylamine and
pentyl-Pyridoxamine compared to Pyridoxamine was borne out in studies where
platelets ...

Classic PAMAM dendrimers have been constructed from a single point on a Pyridoxamine core and terminated with enantiopure N,N-dimethylphenylalanine. Transamination to form phenylalanine and alanine from their related keto acids produced enantioselectivities, induced by the formally remote chiral caps, supporting a computer model that indicates fold...

Wada and Snell (1962a) found that the apoprotein of pig heart GOT catalyzes
both of the following reactions: Pyridoxamine + oxalacetate '1' pyridoxal + L-
aspartate Pyridoxamine + a-ketoglutarate z“ pyridoxal + L-glutamate They also
found a ...

Submitted manuscripts can report any aspect of laboratory, animal or in vitro research.

By Diane B. McColl & Ricardo Carvajal – In response to a citizen petition filed on behalf of a pharmaceutical company, FDA has determined that products containing Pyridoxamine (a form of vitamin B6) are not dietary supplements within the meaning...

Vitamin B6
In a bizarre response to a citizen petition, the FDA has ruled that “Pyridoxamine dihydrochloride or any other compound containing Pyridoxamine” are not dietary supplements within the meaning as indicated by DSHEA, specifically Federal Food, Drug, and Cosmetic (FFDC) Act § 201(ff) and “may not be marketed as such. ”
This FDA pronouncement implicates DSHEA directly because it appears that the agency has determined that there is no “independent, verifiable evidence” of marketing of Pyridoxamine as a food or dietary supplement prior to 1994 when DSHEA went into effect.
